Can someone tell me how I can partition a usb flash drive - windows 7 disk management won't let me and other partition tools say it is not possible to have more than 1 partition
It is a corsair flash voyager 16gb and I want 2 partitions, 1 for PE and 1 for other tools/files
Thanks

As far as i know, it is not possible to create more than 1 partition on a USB device, which isn't detected as a HDD.

dummydisk makes the kernel believe that the USB is an HDD. On other Win systems where dummydisk is absent, the non-first partitions are not visible. On *nix systems, all the partitions will appear.@darren rose

What's the opinion of the BIOS on that, can it boot from the second partition?

Even I didn't know it. Even I forgot that the pen drive was partitioned. I inserted the partitioned pen drive in a Fedora system & fount all its partitions go readily mounted.Interesting! Didn't knew that *nix systems didn't had any problem with that.
So far I can remember, I installed G4D on that device, put some Linux images on the second partition & memory mapped the image during boot. It worked fine. But as with other peculiarities with BIOSes, this might be too specific to my BIOS. I didn't test it on any other system.What's the opinion of the BIOS on that, can it boot from the second partition?

BOOT_USB.exe has Format Stick button which can create usb flash drive with two partitions (use checkbox),Can someone tell me how I can partition a usb flash drive - windows 7 disk management won't let me and other partition tools say it is not possible to have more than 1 partition
but only 1 partition will be visible in Windows.
Then use USB_Part_Flip.exe to change which primary partition of USB-stick is visible in Windows.
In this way you can make the second partition visible in Windows and you can format then also the second partition.

More exactly it is limited to Windows NT based systems.I always assumed, that the limitation of USB-Sticks, which are not recognized as HDD, were of general nature and not just a Windows problem.
Dos, Linux and Windows 9x/Me are "immune" to this.

Do you mean that a Win98 system will recognize all the partitions on USB drive?More exactly it is limited to Windows NT based systems.

Yes.Do you mean that a Win98 system will recognize all the partitions on USB drive?
Is there another possible way to understand what I posted?
This *whatever* that we commonly call "removable bit" is *something* that is read (AFAIK) ONLY by Windows NT based systems , the other mentioned OS simply ignore this "characteristic" of the media, though I cannot say if they don't even read it or read it and then "ignore" whatever values is read.
The "original" thread is here, JFYI:

Udiskhelper does not change my Intenso usb flash drive to fixed.
Maybe I am doing something wrong.
It creates partitions , formats and adds grub fine.
Windows sees the partitions but will only allow access to one.

也许我做错了什么。

How many partitions did you create?It creates partitions , formats and adds grub fine.
Does Windows Explorer show all the partitions? What happens when you try to access partition(s) other than which is allowing access to?Windows sees the partitions but will only allow access to one.

I only made 2 partitions with Udiskhelper.
You can add more with other partition manager.
Windows Diskmgmt sees them correctly as ntfs primaries.
First partition table entry only is accessed as normal drive - can be lettered and seen in explorer.
Trying to access other gives message diskmgmt console not up to date.

Exactly same as my experience.Try in Linux, if possible.First partition table entry only is accessed as normal drive - can be lettered and seen in explorer.

I guess this is because there have three primary partitions on your usb flash drive.
First you should convert one primary partition to an extend partition. Then you can parition your usd drive
